Due to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84849, having
|
|||
|
|
base::NoDestructor<T<U>> and passing an initializer list of Us does not
|
|||
|
|
work if this is not done explicitly, as GCC incorrectly fails to determine
|
|||
|
|
which constructor overload to use:

|||
|
|
|
|||
|

../../net/third_party/quic/platform/impl/quic_flags_impl.cc: In member function ‘bool quic::TypedQuicFlagHelper<T>::SetFlag(const string&) const [with T = bool; std::__cxx11::string = std::__cxx11::basic_string<char>]’:

Explicitly use an std::initializer_list to make the build work everywhere.
